Dark energy may behave like water in a kettle: it only 'boils' after a certain moment in cosmic history. New data show this option isn’t ruled out and, in some ways, might even be slightly more likely than the standard cosmological model.

🎯 If dark energy had 'woken up' too early, just a couple of billion years after the Big Bang, the galaxies and stars we know simply wouldn’t have formed—the expansion would have scattered all matter.
